Subject[PATCH] powerpc: iomap: add missing const to ioread addr argument
ioread*() signatures from include/asm-generic/iomap.h and lib/iomap.c
have been recently modified to add the missing const qualifier to the
addr parameter. This broke the powerpc build which still had ioread*()
definitions without the const (conflicting types).

Add const qualifier to ioread*() definitions from
arch/powerpc/kernel/iomap.c.
